PURPOSE: Provided is a sunblocking, shrinkable film composition which can maintain freshness of food and extend a conservation period, and be used for producing a food container or packing shrinkable film, and can contribute to cost reduction. CONSTITUTION: The composition comprises 3-7 wt% of sunblocking agent, which is at least one selected from 2-(2'-hydroxy-5'-methylphenyl)benzotriazole and 2-(2'-hydroxy-5'-t-butylphenyl)benzotriazole, 0.01-0.02 wt% of non-ionic antistatic agent and the rest of polyethylene resin. The shrinkable film produced from the composition can effectively block a harmful ultraviolet, and finely maintain freshness of food and thus extend a conservation period of food.
